General rate and effective rate in Rumson
New Jersey publishes two rates for every municipality. The general tax rate, $1.049 per $100 in Rumson, is the one applied to the assessed value on the bill: $300,000 assessed owes $3,147.00. The effective tax rate, $1.107 per $100, is "the general property tax adjusted by the municipality's equalization ratio", the rate on market value. Dividing one by the other puts Rumson's assessments at about 105.53% of market value, above market value on average; the state median is 70.02%.
The effective rate is the fairer comparison between towns. On it Rumson ranks 517th of 564, against 542nd on the general rate, and sits $1.030 below the $2.140 median effective rate. At 105.53%, a $300,000 assessment corresponds to roughly $284,279 of market value.

Appealing a Rumson assessment
New Jersey appeals go to the Monmouth County Board of Taxation. Monmouth County is one of the three counties on the alternative calendar, so the petition deadline is January 15 (NJ Division of Taxation). Property assessed above $1,000,000 may go directly to the Tax Court, and a County Board judgment can be appealed to the Tax Court within 45 days. The Board tests the assessment against the common level range: the average ratio plus or minus 15%. Using the 105.53% ratio implied by the state's two rates, that range runs from about 89.7% to 121.36% of market value; the Director's official average ratio for Rumson, which the County Board applies, can differ slightly.
